Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.

Diuretic;  Purgative;  Stomachic.

The dried root is diuretic, expectorant and stomachic[21, 238]. It is taken internally in the treatment of coughs, catarrh and diarrhoea[238]. Externally it is applied to deep wounds[238]. The root is harvested in late summer and early autumn and dried for later use[238]. The juice of the fresh root is a strong purge of great efficiency in the treatment of dropsy[4].
Other Uses
Beads;  Cosmetic;  Dye;  Essential;  Incense.

The root is a source of Orris powder which has the scent of violets[238]. It is obtained by grinding up the dried root[4, 7, 46]. It is much used as a fixative in perfumery and pot-pourri, as an ingredient of toothpastes, breath fresheners etc and as a food flavouring. The root can take several years of drying to fully develop its violet-like fragrance, when fresh it has an acrid flavour and almost no smell[4, 168]. An essential oil is obtained from the fresh root, this has the same uses as the root[57, 61]. The root has been burnt in open fires in order to sweeten the smell of a room[245]. The juice of the root is sometimes used as a cosmetic and also for the removal of freckles from the skin[4]. A black dye is obtained from the root[168]. A blue dye is obtained from the flowers[168]. The seeds are used as rosary beads[61]. Plants can be grown for ground cover, the dense mat of roots excluding all weeds[208].

Propagation
Seed - best sown as soon as it is ripe in a cold frame. Stored seed should be sown as early in the year as possible in a cold frame. A sterile plant, it does not produce seed[233]. Division, best done after flowering though it is usually successful at most times of the year. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.
